FIGS. 1-5 illustrate an exemplary embodiment of a chip card assembly 100 of an electronic device. In FIG. 1, the chip card assembly 100 may include a casing 10, an electromagnet driving assembly 20, and a control unit 30 (shown in FIG. 9). The casing 10 may include a connector 12 therein and define an opening 14. The casing 10 may include a bottom plate 101 and a side plate 103, and the connector 12 may be arranged on the bottom plate 101. The opening 14 may be defined in the side plate 103. The connector 12 may be adjacent to the opening 14. The connector 12 may include a tray 16 and is arranged corresponding to the electromagnet driving assembly 20. The electromagnet driving assembly 20 may include at least one electromagnet 22 and a pushing member 24. The pushing member 24 is arranged corresponding to the at least one electromagnet 22. The pushing member 24 is arranged corresponding to the tray 16. The tray 16 may include a cover 161 for covering the opening 14. The tray 16 may accommodate a chip card 40. The control unit 30 may control the electromagnet 22 to drive the pushing member 24 to move, thereby pushing the tray 16 out of the opening 14.

In FIG. 2, the connector 12 defines an accommodating space 121 and a pair of channels 123. The pair of channels 123 is defined on either side of the accommodating space 121. The tray 16 is received in the accommodating space 121. Each of the channels 123 may receive a corresponding resilient member 125. Each resilient member 125 may include a fixing block 127 protruding out of the channel 123 and into the accommodating space 121. The fixing block 127 may latch in a concave surface 163 (shown in FIG. 1) to latch the tray 16. The connector 12 may include an open end 1211 and a closed end 1213. The open end 1211 is adjacent to the opening 14 and communicates with the accommodating space 121. The closed end 1213 is opposite from the open end 1211 and is coupled to the pushing member 24. In a first embodiment, the pushing member 24 is a sliding member 25 that may slide to push the tray 16. The sliding member 25 may include a main body 251 and a pair of pushing rods 253 extending from a surface of the main body 251 facing a limiting surface 1215 of the connector 12. The limiting surface 1215 is an outer surface of the closed end 1213. The limiting surface 1215 can limit a sliding movement of the sliding member 25. The closed end 1213 may define a pair of chutes 129 corresponding to the pair of pushing rods 253. The pair of pushing rods 253 is received in the pair of chutes 129 and may slide along the pair of chutes 129 to push the tray 16 (shown in FIG. 3).

In FIG. 3, the main body 251 of the sliding member 25 may define a pair of sliding grooves 255. The sliding member 25 may be slidable coupled to an inner surface of the casing 10 through a corresponding pair of bolts 257 received in the pair of sliding grooves 255. In at least one embodiment, the electromagnet 22 is a pair of electromagnets, and a corresponding pair of magnets 259 may be arranged on an outer surface of the sliding member 25 to face the pair of electromagnets. A magnetic force between the pair of electromagnets and the magnets 259 may drive the sliding member 25 to slide along the sliding grooves 255 to push the tray 16. When the electromagnet 22 is not powered on, the pair of electromagnets attracts the magnets 259 to hold the sliding member 25 in position (shown in FIG. 4). The resilient members 125 latching the tray hold the tray 16 in position. When the control unit 30 controls the electromagnet 22 to turn on, the electromagnet 22 generates a repelling force on the magnets 259 to drive the sliding member 25 to slide along the sliding grooves 255, and the pushing rods 253 push the tray 16 (shown in FIG. 5). The repelling force is strong enough to overcome a resilient force of the resilient members 125, thereby unlatching the tray 16 from the resilient members 125 and pushing the tray 16 out of the opening 14. Thus, the tray 16 may be automatically ejected from the casing 10 through the opening 14 by the repelling force, thereby making it easier to remove the tray 16. The cover 161 of the tray 16 may also allow a user to easily remove the tray 16 from the opening 14. The cover 161 may enhance a seamless surface on the casing 10. A waterproof coating may be applied on and around the cover 161 to improve water resistivity of the chip card assembly 100.

FIGS. 6-8 illustrate another exemplary embodiment of the chip card assembly 100. In the second embodiment, the pushing member 24 is a swinging member 27. The connector 12 may define a swinging groove 1217 in a side of the closed end 1213. The swinging member 27 is hinged in the swinging groove 1217. The swinging member 27 includes a driving end 271 and a pushing end 273. The driving end 271 protrudes out of an outer side of the swinging groove 1217. The pushing end 273 protrudes out of an inner side of the swinging groove and corresponds to the tray. The driving end 271 is driven to rotate the swinging member 27 to cause the pushing end 273 to push the tray 16. In detail, the driving end 271 includes a magnet 275, and an electromagnet 22 is arranged facing the magnet 275. The repelling force between the electromagnet 22 and the magnet 275 drives the driving end 271 to rotate the swinging member 27.

When the electromagnet 22 is not powered on, the electromagnet 22 attracts the magnet 275 to prevent the swinging member 27 from rotating, and the resilient members 125 latch the tray 16 in position in the accommodating space 121 (shown in FIG. 7). When the control unit 30 controls the electromagnet 22 to power on, the repelling force drives the swinging member 27 to rotate, thereby pushing the tray 16. A force of the swinging member 27 pushing the tray 16 may overcome a resilient force of the resilient members 125, and the tray 16 may be automatically ejected from the casing 10 through the opening 14 (shown in FIG. 8).

Referring to FIG. 9, the control unit 30 may include a software control module 32 and a hardware control module 34. The control unit 30 may be a central processing unit, a microprocessing unit, or other data processing chip used for storing instructions of the software control module 32 and the hardware control module 34 which are driving programs. In at least one embodiment, when the electronic device is powered off, the hardware control module 34 may eject the tray 16 in response to user operations on the electronic device. For example, when a power button and a volume button of the electronic device are pressed at the same time and held for a predefined time duration, the hardware control module 34 may power on the electromagnet 22 to eject the tray 16. In at least one embodiment, when the electronic device is powered on, the software control module 34 may eject the tray 16 in response to user operations on the electronic device. For example, a user may select a virtual button on the electronic device to cause the software control module 32 to power on the electromagnet 22 to eject the tray 16. In another embodiment, the software control module 32 may power on the electromagnet 22 to eject the tray 16 after a predefined time duration after powering off the electronic device.

The embodiments shown and described above are only examples. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the detail, including in matters of shape, size and arrangement of the parts within the principles of the present disclosure up to, and including, the full extent established by the broad general meaning of the terms used in the claims.
